WIRING DIAGRAMS

The following pages represent the electrical connections wiring diagrams for all the configura-tions supplied with the compressors. On the wiring diagram, outlined with bold lines are the con-
nections already existing on the electrical components (as supplied to the customer). Dotted lines
represent the main connections which must be made by the customer. These include the thermo-
stat, the supply line and the fan motor, if applicable.The connection screws on overload protectors, relays, terminal boxes and ground plates, are sup-plied with a clamping torque of (0.1 0.3 Nm) (1 3 kgcm). For the final tightening during the
wiring done by the customer, we suggest to apply a torque of 0.5 緷 1 Nm (5 10 kgcm) to the
screws. The final clamping torque of electrical connections screw terminals should conform to
the IEC 685-2-2 standard.
